I’ve noticed what seems to be a widespread issue with radar behavior in TWS.
For aircraft equipped with ESA radars, such as the Typhoon and J-10C, the radar incorrectly estimates the target’s relative position when the aircraft is inverted In these situations, the radar tends to interpret the target’s relative angle as being below the aircraft, even when that is not the case.
For aircraft like the Typhoon that have symmetrical radar elevation limits, this mainly results in a tracking logic error. However, for aircraft such as the J-10C and F/A-18E, whose radar upward scan angle is larger than the downward scan angle, this becomes a much more serious issue because it can significantly affect the radar’s ability to maintain track.
Aircraft without ESA radars also seem to have problems in TWS mode. For example, when flying the J-11B, if a target is initially below you and you roll the aircraft so that the target is on the same plane as your wings, the radar still keeps adjusting its elevation downward as if the target were still below. In reality, the radar should return to its default elevation plane relative to the aircraft.
This issue does not occur in STT mode. Target tracking behaves normally when STT is used.
